本発明は、内燃機関用冷却水に添加して冷却水系統の金
属を防錆する防錆剤組成物に関する。DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a rust preventive composition that is added to cooling water for an internal combustion engine to prevent metals in the cooling water system from rusting.
〈従来技術〉
一般に、冷却水が流通する内燃機関の冷却系統は、金属
材料としてアルミニウム鋳物、鋳鉄、鋼、黄銅、はんだ
および銅で集成されており、一方内燃機関の構成材料は
主として鋳鉄とアルミニウム合金とである。したがって
、内燃機関の冷却水系統の防錆剤は、これらの多極類の
金属の全てに対して充分な防錆効果を有することが必要
とされる。<Prior art> In general, the cooling system of an internal combustion engine through which cooling water flows is made of metal materials such as cast aluminum, cast iron, steel, brass, solder, and copper.On the other hand, the constituent materials of an internal combustion engine are mainly cast iron and aluminum. It is an alloy. Therefore, a rust preventive agent for a cooling water system of an internal combustion engine is required to have a sufficient rust preventive effect on all of these multipolar metals.
従来、亜硝酸塩単独あるいは硝酸塩との混合系にリン酸
を加えた防錆剤があるが、この防錆剤は、冷却水に添加
した場合に激しく ＮＯｘが発生して好ましくない。ま
たリン酸に代えてメルカプトベンゾチアゾールのナトリ
ウム塩を加えた防錆剤もあるが、メルカプトベンゾチア
ゾールのナトリウム塩は高価であり、工業的利用には好
ましくない。Conventionally, there are rust preventive agents that include nitrite alone or a mixture with nitrate and phosphoric acid, but when added to cooling water, this rust preventive agent generates a large amount of NOx, which is undesirable. There is also a rust preventive agent in which a sodium salt of mercaptobenzothiazole is added instead of phosphoric acid, but the sodium salt of mercaptobenzothiazole is expensive and is not suitable for industrial use.
さらに前記のように内燃機関の主な構成材料は、鋳鉄と
アルミニウム合金とであり、冷却水によるそれらの腐食
性が異なるために、それらに対して同等の防錆効果を有
する防錆剤でなければ、内燃機関の主な構成材料によっ
て防錆剤を使い分けなければならないという不都合が生
じる。しかしながら現在そのような内燃機関を構成する
多種の金属材料の全てに対し同時に充分な防錆効果を発
揮するような防錆剤はほとんどない。Furthermore, as mentioned above, the main constituent materials of internal combustion engines are cast iron and aluminum alloy, and since the corrosiveness of these materials by cooling water differs, a rust preventive agent must have an equivalent rust preventive effect on them. For example, there is the inconvenience that a different rust preventive agent must be used depending on the main constituent materials of the internal combustion engine. However, at present, there are almost no rust preventives that simultaneously exhibit sufficient rust preventive effects on all of the various metal materials that constitute such internal combustion engines.
また、冷却水系、なかんづ〈ラジェータ部分においては
熱伝導性の良い銅や黄銅の細い部品で構成されておシ、
その接続部分をはんだ溶接することにより苫閉構造を形
成している。すなわち、はんだはラジェータ部分にあっ
てはシール剤の役目を果たしており、はんだが腐食され
ラジェータの密閉構造が崩れると、内燃機関の冷却機能
が失なわれることになる。In addition, the cooling water system and radiator part are made of thin copper and brass parts with good thermal conductivity.
A closed structure is formed by soldering the connecting portions. That is, the solder serves as a sealant in the radiator portion, and if the solder corrodes and the sealing structure of the radiator collapses, the cooling function of the internal combustion engine will be lost.
〈目的〉

An object of the present invention is to provide a rust preventive composition that effectively rust-proofs the cooling water system of an internal combustion engine and various maple materials constituting the internal combustion engine at low cost without generating Ox.

材料を充分効果的に防錆できることを見出した。As a result of intensive research to achieve the above object, the inventors of the present invention have developed an addition salt of benzo) IJ azole and a water-soluble amine (hereinafter referred to as BT and SA), containing nitrate and phosphate. In addition, they discovered a rust preventive composition containing at least one of an addition salt of tert-butylbenzoic acid and a water-soluble amine (hereinafter referred to as TEA or SA) and a benzoate, and completed the present invention. That is, by adding the rust preventive composition of the present invention to cooling water for internal combustion engines, NOx
We have discovered that it is possible to sufficiently and effectively rust-proof many types of metal materials that make up internal combustion engines without causing any corrosion.

。Examples of water-soluble amines include monoethanolamine, jetanolamine, triethanolamine, cyclohexylamine, and isopropylamine. B.T.
SA has an excellent rust-preventing effect on copper and brass, and the amount added to the cooling water is 0.01 to 2.0% (the same applies below weight%), preferably 0. 05-1.0%. If the amount of cooling is less than 0.01%, the rust prevention effect on copper and brass will be poor, and on the other hand, if it is added in excess of 2%, the rust prevention effect will become saturated and it will be uneconomical. It becomes dark brown and results in a decrease in commercial value. Examples of nitrites used in the present invention include sodium nitrite, potassium nitrite, etc., and the amount added is 0.03~
The thickness is 1.5 inches, more preferably 0.05 to 1.0 inches. If the amount added is less than 0.03 inch, the rust preventive effect on L cast iron and steel will not be exhibited, and it will be particularly inferior to cast iron. On the contrary, 1

+Thorium, potassium benzoate, etc. are added, and the amount added is 0.05 to 1.0%, making it more preferable.
It is o.2 to 0.5 chi. Benzoate has an excellent antirust effect on solder, and when mixed with phosphate, TEA, and SA, this effect is further enhanced. If the amount of benzoate added is less than 0.05 inch, the rust preventive effect against rust will be poor, and on the contrary, if it is added in excess of 1.0 inch, no improvement in the rust preventive effect will be seen. The rust preventive composition used in the above may also contain a borate. The borate salt is preferably a sodium salt, which reduces pH fluctuations due to the buffering effect of the rust preventive solution. The amount of borate added is 0.0.0'
1 to 0.7%, and if this addition is less than 0.001%, the buffering effect of the rust preventive solution will be poor, and conversely, 0.7%
If it exceeds this value, the antirust effect on cast iron will be inhibited, and the buffering effect will be saturated.
